p= and d= can appear individually or together. If either p= or d= appear, then u=, y=, a=, and b= are ignored.

If both a= and b= appear then both upper and lower bounds are honored.

When multiple time-related filters are used, e.g. ym, yw, and ymd, which one(s) is/are applied is unspecified and may change between fossil versions.

CHECKIN or TIMEORTAG can be a check-in hash prefix, or a tag, or the name of a branch.
